Letters Patent No. 98,304. dated December 28,1869.

mraovnn CHEWING-GUM The Schedule referred to in those Letters-Patent and making part of the same.

To all whom it may concern.

Be it known that I, W1LLIAM F. SEMPLE, of Mount Vernon, county of Knox, and State of Ohio, have invented a new and improved Chewing-Gum; and I do hereby declare that the following is a full, clear, and exact description of the same.

The nature of my invention consists in compounding with rubber, in any proportions, other suitable substances, so as to form not only an agreeable chewin g-gum, but also, that item the scouring-properties of the same, it will subserve the purpose of a dentifrice.

It is well known that rubber itself is'too hard to be used as a chewinggum, but in combination with nonadhesive earths may be rendered capable of kneading into'any shape under the teeth.

In the manufacture of thissimpr'ovedchewing-gum, no vulcanizing-process is employed. It is produced by simply dissolving the rubber in naphtha and alcohol, and when of the consistence of jelly, mixing with it prepared chalk, powdered licorice-root, or any other suitable material, in thedesired proportions, and subsequently evaporating the solvents.

I do not, however, confine myself to this method alone for the manufacture of the gum. For commercial purposes, other equallyefl'ectual processes may be used font-he uniting of the rubber with suitable substances.

Instead of the solvents named, any other that will soften the rubber, without being oflensive, may be em-' ployed, such as parafline, spermaceti, wax, gums, resins, and the like. Any of the materials commonly used for the manufacture of dcntifrices may be combined with the rubber, 'such as orris-root, myrrh, licoriceroot, sugar, barytes, charcoal, 8w.

By the term rubber, Iwish to include the allied vegetable gums, which are ordinarily known as the equivalents of caoutchouc.

Having thus fully described my invention,

What I claim as new, and desire to secure by Leta ters Patent, is-

The combination of rubber with other articles, in any proportions adapted to the formation of an acceptable chewing-gu m.
